I must have been reading and listening to various incarnations of the Hitchhiker's Guide to the Galaxy for nearly 30 years now. I've re-read all the books, listened to the radio series, watched the TV series and film and played the adventure game. I'm currently reading the books to my daughter. Sadly Douglas Adams died tragically young and so didn't get the see the (disappointing) film completed, or finish the third Dirk Gently book. Now the H2G2 series has been continued by Eoin Colfer whose Artemis Fowl books my daughter also enjoys.
This volume continues the adventures of Arthur, Ford, Zaphod and Trillian with more Vogon encounters, some deities and various other species. The style is similar to that of the later DNA books with lots of extra little details. It was enjoyable, but lacked a certain spark. I felt there wasn't enough of Arthur. Maybe I identify with him, Sign of middle age? It's worth a read if you have read the others, but may be confusing if you haven't. Friends can borrow my copy.
I'm currently reading Terry Pratchett's Unseen Academicals. This time it's about football and is also fun. Full report when I find time to finish it.
In parllel I'm also reading Cory Doctorow's Someone Comes to Town, Someone Leaves Town. I have this as an ebook on my phone from Feedbooks. It's there to pass the time when I and stuck somewhere with nothing else to do. It's a good, geeky read about our evolving society, with some magical elements.
